Rip-saw trough



Patented Oct. 28, 1930 U T D STATES Application filed Aug'ust 21, 1929. Seria1 No."387,35 2."

My present invention relates to a new and ticularly to a'rip trough of simple construction which may be readily used in connection a with 'a plurality of independently operating saws. j 1

The object of my invention is to provide'a new, novel, simple andinexpensive rip saw trough which may be readily disposed be tween a pairof board sawing machines. 1 Another object of my invention is to prothe above character, a novel arrangement of a guide members whichwill serve as the boards are passed thereoverto turn the latter and cause them to be presented to a second sawat an" angle. diiferent from that at which they passed throughfthe preceding saw.

Forthe purpose of facilitating an under standing of my invention, I have shown by way of illustration and not of limitation, a.

rip saw trough which embodies the several aspects of my invention.

' In the drawing- 3 j Fig. 1 is a view in perspective, looking downwardly upon my improved rip saw trough, and V Figs. 2, .3, 4, 5, and 6 are sectional views takenvupon' the corresponding section-indieating lines appearing on Fig.1, looking in thedirection of 'arrowsr v p v In Fig. 1 of the drawing, 10 designates a i portion of my improved rip saw trough which is in the nature-of a horizontally disposed flat supporting member. This member 10 is adapted to be supported at its ends between the two saw machines 11 and 12, sov that its upper surface will lie on a level with the bedplane of the twosawing machines 11 and 12. This arrangement of the member 10 is accomplished at its right hand end by means of overhanging hooks 13 which rest upon the surface of the machine 12, and at its left hand end by means of the projecting ends of a pair of spaced guides 14 and'15 ,which are to be'i'described greater detail improved type'o'f rip trough and more parhereinafter. At the right hand end of the member 10 adjacent the saw 12, there isillustrateda pair of oppositely disposed guides and-17 which may be adjusted; to "any de- "SIIQd degree of separation. -Thesev guides 16 "and 17 areadapted to receive a number of boards in an edgewise-manner as" they are dlscharged from the saw. 12 and gulde them 111 this manner as they are' 'pushed .overthe member 10 between the members-1 1 and 15. vide in connection with a rip saw trough of 7 .At the 1 right hand. end of the ;members 14; and '15 Where the boards are presented, as previously stated, in an. edgewise m'anner, there are provided respectively upon the. guides 14 and 15 suitable cleats 18 and 19. These cleats 1-8 and19 are of such configuration and are so disposed that as thenboards advance therebetween, they will be inclined out of their vertical edgewise position until, whenthey are finally dischargedtherefrom,

NT' 'Q' YF CE they will bearranged in 'a' horizontaledgewise position, one abovethe other,'and when finally discharged from the member "10 will be presented to the saw 11 so that they will be sawed again at an angle to that'at which 7 they were originally sawed bythesaw 12. The guides 14, 15,16 and 17 are shown as held in position by suitable brackets 20 which are adjustably held upon the member 10 by means of bolts 21- so that the guides may be disposed with differentdegrees'of separation, as determined bythe thickness and width of the boards being sawed. v e V For a better understanding ofthe mode of operation ofmyimproved rip saw trough, reference should 'be hadto Figs. 2, 3, 4, 5

and 6, Wherein'it-will be-seen that the boards designated by the numeral 22 are tipped from a vertical position to a horizontal position in progressing through the trough from the point'illustrated in Fig. 2 to the point illustrated in Fig. 6. In Fig. 2,-which corres onds to the point where the boards enter aetween the guides 16 and 17 theping of the boards caused by the cleats 18 and 19 before they have passed out from be- 'in'th'e appended-claims.-

boards 22 are shown as in their vertical position, the boards 22 in this illustration being fourin number and having been produced by passing a block of slightly larger dimensions through a set of three saws which have served to slice the block into four distinct boards of a predetermined thickness. As the boards 22 reach the point illustrated in Fig, 3, it'will be seen that they will be allowedto tilt slightly to one side and that, as they reach the point illustrated in Fig. 4:, they will be delinitely inclined to apredetermined angle by the cleats 18 and 19 upon the guides 14 and 15, and that,

as they advance turtheralong between the cleats 18 and 19, they iwill be'tipped'to' almost horizontal position,as illust ateel in- Fig.5, so that when they have finally advanced to the point illustrated in Fig. 6' they will readily assume a horizontal position, one above the other, and thus be'in a position where, with a singlesaw or number of saws, y may be again sawed to apredetermine d width. r

In illustrating my invention,I have shown a trough which is particularly adapted to relatively shortlengths of board; but it will be readily understood that by lengthening the various parts and properly spacing the J cleats 18 and 19 with respect to the guides 16 and 17, it will' be possible to guide and rearrange boards of substantially any length, 'the only consideration here being that the position of 'thecleats 18 and 19 be su-iiicient- 'ly distant from the ends ofthe guides 16and 17 to cause a tipping of the boards only after their trailing end has passed through the guides 16 and 17 for otherwise any tiptween the guides 16 and 17 Would tend to cause them to bind in the trough.

In order to prevent the accumulation or saw-dust in the trough formed as above outlined, I have provlded suitable sawdust dis-' charging apertures 23 and 2st, the aperture 23 lying between the guides 16 and 17 and the aperture 24 between the guides 14 and 15.

In conjunction with the discharge end ofthe trough between the guides l i and lf), I have also illustrated a wed'ge lilre member '25 which is adapted to cause the pieces of lumber 22 to align with their edges in alignment so that when they are presented to the saw 11, the boardswill be sawed to a uniform width. In other words,- the wedge-like member 25 is a'daptedto-guide theboards over against the guidem'emb'er'l l.

1W hile I haveshown the" preferred form of my lnventlon *as now 'known to me,1t is to be understood that various changes may be made in its construction wlthout departing from the spirit of the invention as defined Having thus described my invention, what I claim and desire to secure by Letters Patcut is:

1. A rip trough for board sawing machinery comprising a member adapted to be supported at each end between two saw machines, adjustably spaced vertically eXtending guides upon said member forming a trough thereupon through which lumber may pass, and means carried by said guides adapted to turn the lumber through an angle of ninety degrees as it passes through they trough.
